To all whom it may concern:

Be it known that I, HULEN BRAZEAL, a citizen of the United States,residing at Harrison, in the county of Boone and State of Arkansas, haveinvented certain new and useful Improvements in Automatically-OperatedFarmGates, is a specification.

This invention relates to farm gates and more particularly to vehicleactuated gates of this character.

The object of the invention is to provide a simply constructed,automatically opened and closed gate, the operating parts of which areamply protected to prevent rust and the consequent inoperativenessincident thereto.

Another object is to provide operating means for a gate of thischaracter located entirely below the surface of the earth and havingplatforms for engagement by the wheels of the vehicle for opening andclosin the gate.

- ith the foregoing and other objects in view, which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed may be made within thescope of what is claimed without de arting from the spirit of theinvention.

11 the accompanying drawings Figure 1 represents the rear end of a gate'and its supporting post with the latter shown broken out and theoperating means of the gate shown in longitudinal section,

Fig. 2 is a front elevation of the gate with its actuating mechanismshown in trans verse section, and

Fig. 3 is a detail horizontal section taken on the line 3-43 of Fig. 1.

In the embodiment illustrated, a gate G of ordinary construction isshown having the usual front and rear uprights U and U", respectively,and which is mounted to swing between front and rear posts P and P.

' The rear upright U has a shaft 1' extended longitudinally therethroughand projected at its opposite ends'beyond the ends of said uprights.This shaft 1 is provided wlth reduced terminals 2 forming journals forthe shaft and which are engaged with hearings in arms 3 and 4:which'extend laterally inof which the following to be engaged ward fromthe upper and lower ends of the rear post P. Another arm 5 extendslateral y from the lower end of shaft 1 and is provided at its terminalwith an eye 6 for a purpose presently to be described.

The post P may be composed of any sultable material and is here shownc0mposed of wood with its lower end pointed and embedded in a concretebase B which has a well or socket 7 arranged in front of the post intowhich projects the lower arm 4 and the lower end of shaft 1 as is shownclearly in Figs. 1 and 2.

Extending laterally in opposite directions from the well or chamber 7are two conduits 8 and 9, preferably composed of metal pipes althoughobviously they may be made of any other suitable material. Theseconduits 8 and 9 are arranged in longitudinal alinement and may be ofany suitable or desired length according to the distance at WlllOll itis desired to position the elements by a vehicle for opening and closingthe gate.

These conduits open at their outer ends into Wells or chambers 10 and 11located on opposite sides of the gate and which are covered bydepressible platforms 12 and 13. These platforms are hingedly connectedat their inner ends to suitable supports 14 mounted within the wells 10and 11 at their inner ends. As shown, the platforms are provided attheir inner ends with depending apertured lugs 15 through which thehinged pintles 16 pass and connect forms to their supports. 7

These platforms 12 and 13 are provided at their free ends 'on theirlower faces with eyes 17 with which are engaged links 18. These links 18connect said platforms with one arm of hell crank levers 19 which arefulcrumed at 20 on the bottoms of the wells in which they are mounted asis shown. clearly in Fig. 1.

Rods 21 and 22 connect the free ends of the other arms of said bellcrank with the eye 6 carried by the arm 5 of shaft 1 as is shownclearlyin Fig. 2

By so connecting these platforms with the axle or shaft 1 on which thegate is de. signed to swing, it will be obvious that when the platform12 is depressed by the passage thereover of a vehicle wheel or by aperson or animal stepping thereon, a pull will be exerted on rod 21which will operate the plat- Mitt to swing the gate into open positionand to raise platform 13. After the vehicle passes through the gate andthe wheels thereof engage the platform 13, it will be lowered andthereby operate through rod 22 to return the gate to closed position.

It will also be understood that when a vehicle approaches the gate fromthe opposite side, the wheels thereof will depress platform 13 andthrough link 18, bell crank 19, and rod 22 connected therewith, will 0en the gate G in a manner similar to that 1ust above described, and thatthe closing operation at the other side of the gate will be effected inthe same manner by the depression of platform 12.

From the foregoing description, taken in connection with theaccompanying drawings, the advantages of the construction and ofthe'method of operation will be readily apparent to those skllled in theart to Whic the invention appertains and while I have described theprinciple of operation of the invention together with the device which Inow consider to be the best embodiment thereof, I desire to have itunderstood that the device shown is merely illustrative and that suchchanges may be made as are within the scope of the claimed invention.

An inspection of Fig. 1 will show that the conduits 8 and 9 and all theactuating parts for opening and closing the ate, except the platforms 12and 13 will be posed underground and the platforms closing the wellsLeaders 10 and 11 operate to protect the contents thtiregf thusperformin' g a double function.

e am:-

In a gate of the class described, the com-- bination of a supportingost, a chamber arranged in front of sa1 post at the base thereof, armsextending laterally from said post at its upper and lower ends, one ofsaid arms projecting into said chamber, conduits leading from saidchamber in opposite directions and in longitudinal alinement, wellsarranged at the outer ends of said conduits and communicating therewith,closures for said wells, hinged at one end to the inner side walls ofthe wells at their upper ends, other ends of said closure bein adaptedto swing downwardly into the we s, stops for limiting the downwardmovement of said closures, an arm extending laterally from the lowerpintle of said gate, rods connected at one end with said arms andextending through said conduits into the wells, links depending from thefree ends of said closures, and bell cranks fulcrumed in said wellbetween the outer ends of said rods and said links and connected attheir free ends with said rods and links whereby the depression ofeither closure operates to open the gate.

In testimony whereof I afiix my signature in presence of two witnesses.
